The purpose of this study is to investigate the safety and feasibility of administering investigational drugs (meaning not Food and Drug Administration (FDA)-approved for kidney cancer) prior to surgical treatment for kidney cancer. The first drug is called MEDI4736, and the second drug is called tremelimumab. Both of these drugs work by attaching to certain proteins on immune cells with the goal of stimulating an immune response against cancer cells. This is a phase 1 trial, with the primary goal of identifying if this treatment is safe and possible side effects when given prior to surgery for kidney cancer.
